MOTOR-'VEHICLE DEVICE.

Specification of Letters Patent. Patented Sept. 30, 1919,

Application led September 17, 1917. f Serial No. 191,717.

To all whom t may concern: f Be it known that I, GEORGE W. KELLOGG, of Rochester, in the county of Monroe and State of .New York, have invented certain new and useful Improvements Motor- VehicleV Devices; and I do hereby kdeclare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of vthis specification, and to the reference-numerals marked thereon.

My invention possesses several objects in the improvement of motor vehicle operation,

and has to do with giving ample notice of the temperature conditions under which the engine is operating and also increasing the eiiciency of the engineby keeping the valves and cylindersy continually clean and securing more perfect combustion. Inv a more particular aspect, the principal obj ect of my invention is to provide a temperature inf` dicator controlled by the lengine water jacket at its hottest point, and located so as to make it possible for the driver to obtainl a reading easily under all conditions andv at any time, without getting out of his seat. An additional object resides in utilizing air, or a mixture of Y air, with steam from the engine water jacket,

to eect the temperature indication, and carrying `this same air and steam, or a1r alone, to the-intake manifold for decarbonizing the engine and improving the combustible mixture. To these `and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel featuresy being pointed out in the claims at the; end of the specification.

In the drawing: Y Figure 1 is a side elevation with parts appearingvin section showing the constructionof my improvements -a-nd'their application toa usual type of motor vehicle and, Fig. Qyis a transversesection in a vertical plane through the steam expansion dome,

Fig. 3 is a horizontall section on the center line of the valve 28. Y Y The structure is applicable to various form of motor vehicles, andI have illustrated a conventional form of automobile merely by way of example, omitting the body and running gear which is unnecessary, to an vunderstanding of my invention. lIn the structure shown, 1 designates the enginel provided with the'exhaust manifold 2 'and jacket mixed with air, or by air alone, which is furnished to a conductor -that passes through the engine water jacketat a point subject to the maximum heat when in regu-- lar operation. Thus I obtain an indication of the true condition of the engine, or in other words, a knowledge of its condition at the f hottest point.

The conductor referred to embodies a pasl sage 9V which extends from a steam expansion dome 10 downwardly through the water jacket, and thence upwardly and connects with a pipe 11. The dome 10 has side walls 23 of wicking or similar porous material reta-ined by perforate metal plates 24 to ad# mit air, which is filtered as it enters. An inlet tube 25' is ,arranged in the dome 10, and

communicateswith the -passage 9, for supply'- ing air thereto, while 26 isa passage leading upwardly from the water jacket to the expansion dome, and carryingy thereto a supplyof steam which is mixed with the incoming filtered air entering through the porous side walls, and carried thence into the passage 9. The mixture of air and steam. travels through the passage 9, and is' subjected toV the heat of the water jacket before entering the pipe 11. The dome 10is high enoughV above the water cooling system level to ordi narilyjprevent wat-er from backing up into it, but incase of an excessive water column, the water will` overiiow the walls 27, and be prevented from entering inlet 25. which is above the top of said walls 27.

The pipe 11 is coiled, as shown, topermit expansion andv contraction, land communi` cates with a chamber 12, formed in a casting or support 13 mounted upon the instrument board. The dome l0 permits the steam to spreadl and expand, eliminating the surplus moisture more or less, while the expanded hot vapor mixed with air, travels on the heat responsive element is located. By

to the heat'responsive element, Vand thus an improved combustible mixture of airand steam is secured. y f .l

The bulb '8 of the thermometer is located in the chamber 12, and the latter-:is 'COIL- nected through'a port 16 and a passage 17., with a conducting pipe 18 WhichleadS .DO the intake manifold B. As the engine becomes heated and the Water in the' circulating system converted into steam, this steam risesin the passage 26, entering the dom-e 10, Where? it is expanded and mixed with an adequate airsupply. This mixture is'again subjected to the heat vof the Water-*jacket and then passes to the chamber in'j which observing thetliermometer at any given moment, the temperature of the Water-at the hottest point ofthe circulating system can belnoted.

The air and steam may be drawn tothe thermometer chamber in various Ways, as

, by pressure o'r suction, mani'ially controlled or automatic,` and I prefer to do this by "utilizing the suction of the engine, connecting the tl'iermometei"y chamber With the intake manifold' as Aalready mentioned. They steam rises into the dome r10, Where it expands, -and ther air and steam mixture isy I then drawn in contact, With` the vheat respons- .ive element by the suction of the engine,

after WhichV it 'passes through thev port 16- and passage 17, Vand is drawn thence to the intake manifold 3. vThe supply off Water "entering the intake manifold in a hot vaporous condition is of considerable assistance inv securing more perfect combustion as Well recognized by explosive engine engineers,

and also serves Vin a lmost effectual Way to, constantly cleanl the valves and interior engine parts. Different" atmosphericl 'conditions, however, make it desirable to feed the steam to' thef'in'let manifoldl in varying' quantities; Toa'ccomplish this, I ein-ploy adjustable steam supplying means inthe form ofv a manually controlled valve 19, whichA is V'movable toward and from the'port'l. -The V.hicle isV moving to suit-the variance-of 'con-- ditions under Whichthe engine Vmay be ovp--I Y adjustable valve y19-is located in the support 13 upon the instrumentboard-and is thus Within easy reach of the driver, Yand can bef;

positioned' at; any desired point While, a ve'- erated'. v f -l Y Incase it be desired `to eliminate the steam supply,"andy furnish only air'to the intake manifold, the passage 26l can be closed byi valvef28,liso that only air Will be' drawn into passagei), and the air Will-'be suliiciently heated inipassing` through the Water jacket to frivea proper temperature indication.Y

The 'scope of myinventioii is not to 'be determined VVby the precise form or arrangementof 'pa 1ts shown, since the underlying principle of'operation may be carried 'out in a variety ofways. I I intend tocover by this application any modified arrangement Which may iiicorpoigatethesalient idea lof carrying air or steam orviboth into contact with the liQiitestipQrt-ion of an engine Water cooling system and thence to a heat responsive element, Withfrthe Vtemperature indicatory locatedy Within closeyiew of the vehicle driver, and; furtherxin` utilizing the suction of the enOine for circulating the air and steam and feeding it in desirable proportions .to the engine, alonggwith the combustible mixture.
